Croix terrane was apparently thrust over the Fredericton sequence and is at least parautochthonous
locally, if not allochthonous.
From a palaeoecological point of view, they probably correspond to demic organisms, dwellers of relatively deep environments and autochthonous or parautochthonous
taphonomic elements (sensu Fernandez Lopez, 1990; 1991), deposited during periods of reduced sedimentation in a low-energy environment.
Valves are rarely found in their life position and appear as parautochthonous
associations (transported slightly in the vicinity of their habitats (Seeling and Bengtson, 1999).
Howard and Offield 1968; Robertson 1968; Roddy 1968; Wilson and Stearns 1968] have demonstrated that parautochthonous
bedrock exposures of shatter cones are confined to the central uplift of complex craters.
The application of size-frequency distribution and energy flow in paleoecologic analysis: an example using parautochthonous
death assemblages from a variable salinity bay.
A more recent view is that the granite massifs are parautochthonous
In this case valves are rarely found in their life position and appear as parautochthonous
associations (transported slightly in the vicinity of their habitats (Seeling and Bengtson 1999).
This implies that both parautochthonous
and allochthonous elements (sensu FernAndez Lopez, 2000) are probably mixed together in the fossil association of Lano; palaeoecologically, there are demic elements, consisting of aquatic (bony fish, amphibians) or semi-aquatic elements (crocodyliforms, chelonians) and also ademic, terrestrial ones (solemydid turtles, dinosaurs, mammals).
In an important paper, Wnuk and Pfefferkorn (1984) described parautochthonous
assemblages of medullosan pteridosperms from Pennsylvania, USA.
A marginal parautochthonous
belt in the northwest can be readily linked with the adjacent foreland, despite the effects of Grenvillian metamorphism and polyphase deformation (Fig.
